Electrode 10 can be electrically connected to the electroactive element for applying electrical power thereto. When power is applied to the component below a first predetermined threshold, the component may have minimal optical power. When power is applied to the component beyond a second predetermined threshold, the component may have maximum optical power. The fixed optical power may be greater than the maximum optical power. In this manner, the fixed optical power provides most of the optical power of the elastic electroactive crystal.

In the illustration, the electroactive elements 6a, 6b & 6c may comprise electricity separated by an insulating material 128668.doc -13 - 200848001 24 (eg, a flexible dielectric film) A layer of active material i6. In Figures 4A and 4B, the electrically active elements may be less rigid, resilient or elastic than the outer casing. In Figures 4A and 4B, the elements of the electro-active elements may have a variable index of refraction and may be individually activated. Since the electroactive elements are insulated from each other, one or more of the electroactive elements can be selectively or in any combination. By doing so, it is possible to have a combination of additional optical power or to provide - single-optical power. This allows the optical power of an optically stacked multilayer of crystals or optics to be one of the electroactive elements after the surgical implantation. The electrically active elements are activated in response to a control # from an external source of the electroactive crystal. Referring to Figures 5A, 5B, 5C and 5D, the electro-active crystals may include a receiver, such as a sensing device and/or a memory metal, for receiving a control h number from an external source of the crystal. The chirp control signal can be used to modulate the power applied to the various components of the components for remote tuning of their optical power. Referring again to Figures 4A and 4B, the electrically active elements can be stacked and individually activated for varying the total optical power of the electroactive crystal with any combination of the variable optical powers of the elements. In Fig. 4B, the electroactive crystal cell comprises electroactive elements 6a, 6b and 6c which, when activated, have exemplary optical powers + 〇25D into 0.25D, +0.50D or -0.50D and +2.50D, respectively. +1.25D. For example, the elements can be activated in various combinations for a minimum optical power of +0.25D or -0.25D (by example only by initiating the 128668.doc -14-200848001 + 0.25D that is always required) -0.25D) to a maximum optical power of +5 5〇D (by example only by starting a +0.25D, a +0.50D, a +2.5〇D and a 25D

In this example, the electric/tongue water body b has an optical power that increases by 0.25 D (positive or negative) between the minimum and maximum powers. When the elements of the elements are individually activated in appropriate combinations, the elements can provide an increase in optical power variation and the total optical power of the electroactive crystal can be tuned to the desired optical power. The incremental change in optical power in this example is 〇 25D, but in certain other specific embodiments it is 0.12 〇. These components are adjustable for providing near, medium and/or long range viewing corrections. It will be appreciated that the values used herein are intended to be exemplary so that different optical powers, increments and/or numbers of optical power variations of the electro-active elements can be used (e.g., for adapting the eye to a limited size). In the present invention, the elements may be pixelated in one or more of the elements. The electrodes can apply power to the pixelated elements. By shunting specific electrodes, approximately 50% of the maximum optical power of these components can be provided. In the above example, element 6c can provide a maximum optical power of +2·5 〇Ι) and a reduction of 50% optical power by a +1.25 D. - or a plurality of components of the electroactive element may comprise - modal elements. The modal element can change the optical power when a potential gradient is applied to a variable focus mode crystal. The modal element can use, for example, a liquid crystal to produce an inductive optical device. Referring again to Figures 4A and 4B, the electro-active elements, 仏, 〜 and Μ may comprise a combination of polymer dispersed liquid crystal and bistable liquid crystal. The bistable crystals can be tuned to obtain a desired optical power when sufficient power is applied to the elements of the components at noon (eg, across the electrodes) 128668.doc -15-200848001 The polymer dispersed liquid crystals can be cured or fixed distally within the element after the desired optical power is set. Curing the crystals fixes the orientation of the molecules for stabilizing the tuned optical power while positioning or embedding the electroactive crystals in the eye. An electromagnetic signal (e.g., a laser) having an eye-safe wavelength (e.g., 15 4111 wavelengths) can be used, for example, to remotely cure the crystals using a pair of wavelength-sensitive initiators of the electromagnetic signals. The polymer dispersed liquid crystal may comprise, for example, a mixture of a nematic liquid crystal mixture E7 ("produced") and a uv cured optical adhesive NOA65 (manufactured by N〇rland pr〇ducts). In a specific embodiment When the electroactive crystallite is embedded in the eye, the bistable liquid crystal can be tuned distally and the polymer can be cured distally using a device positioned outside the eye. The bistable liquid crystal material can be used to reduce power supply over time. The amount of power consumption required for the electroactive crystallite. When a suitable first voltage exceeding a first threshold is applied, the overall orientation of the liquid crystals of the individual bistable liquid crystals may be maintained by removing the voltage The first voltage induced by the first voltage may be returned to its original state by applying a second voltage lower than a second predetermined threshold. The bistable liquid crystal may include, for example, surface stabilized ferroelectric Liquid crystal (SSFLF), which is a one-layer liquid crystal. The use of a bistable liquid crystal reduces power consumption because voltage can be used to switch the device between its states and generally does not maintain such operations. 5A, 5B, 5C, and 5D each show a front view of an elastic electroactive crystal 2 having an elastic electroactive material. The elastic electroactive crystal comprises an elasticity embedded in the electroactive element.

For example, the electroactive crystallite can be folded for Inserting all the mouth lice in the eye. Once the electroactive crystallite is released in the eye, the memory metal material can unfold the crystal to its deployed state for operation in the eye. Referring to Figures SC and 5D, the electroactive crystal can be Including - a controller and / or drive electronics 12 and electrical connections 14.

Referring to Fig. 3, the electrodes are at least conformed to the surface relief diffraction pattern 2 of the first film 8a. Referring again to Figures 5A, 5B, 5C, and 5D, the electrodes can include a plurality of concentric electrode rings. When the electrodes apply electrical power to an electroactive element having such a ring, the element may thereby have diffractive optical properties. In the present invention, the electrodes can be turned on and off in less than about one (1) second. The electrodes may be composed of a single material or a metal material (for example, inscription), an optically transparent material (for example, indium tin oxide (IT〇)), and a conductive organic material (for example, jing (3,4-methoxyethylthiophene). Composition of p-styrenesulfonic acid) (ped〇T:PSS) and/or carbon nanotubes. The electrodes can be coated and wrapped around the liquid crystal material. The transparent material may comprise fine metal traces, such as silver or stencil, for 4 plus V. Power can be applied across the transparent electrodes to alter the optical properties of the electroactive crystal, as described herein. The electrode layer may have a thickness of, for example, less than 1 μm, but is preferably less than μ. The controller and/or drive electronics 12, power source 26, memory metal material 28, and other electronic components can be coupled to the electrodes by the electrical connections 14. The 128668.doc -17- 200848001 connection may include smaller wires or traces, which may also be transparent. These electrodes and electrical connections may be elastic. Referring to Figures 5B and 5D, the electroactive crystallites may include a kinetic energy 50 electrically coupled to the electroactive element for converting the motion of the eye into electrical power to provide electrical power to the electroactive element. The kinetic energy driver can include a conductor and a permanent magnet located within the driver. Electric power is generated when the conductor moves relative to a magnetic field generated by the hydrodynamic magnets. Such drives are well known to those skilled in the art and are generally used in non-battery powered watches. For example, an eye movement rechargeable power source 26 such as Rapid Eye Sleep (REM) (e.g., during a sleep and/or wake cycle). Referring to Figures 5A and 5B, the electroactive crystallite may include a piezoelectric film 48' for generating electrical power. The piezoelectric film is adapted to connect the electroactive crystal to an eye structure. The tension of the piezoelectric film can be changed by the movement of the eye. The film converts the change in tension into electricity. For example, when the piezoelectric film can be attached to the ciliary body, the iris near or on the pupil, and as the pupil enlarges and/or contracts, the piezoelectric film will stretch and relax, thereby generating electric power. Referring to Figures 5A and 5C, the power can be generated using a photovoltaic cell of sensing device 32. As is well known in the art, the photovoltaic cell converts solar energy into electricity. The photovoltaic cell is tunable for charging using, for example, a 15 μηι infrared laser source (not shown) positioned outside of the electroactive crystal. The laser can be mounted, for example, on a pair of glasses that are adapted to charge the power source when worn by a user. In various embodiments of the specific embodiments, the generated power may be stored in power source 26. The power source can include a battery, such as a thin film, which can be rechargeable and/or flexible. The thin film battery can be inductively charged by remote charging. In one embodiment, an inductively enabled pillow (not shown) provides an inductive charge while the user of such electroactive crystallite is sleeping. In a specific embodiment, the memory metal material 28 can be used to bias the electroactive liquid crystal to an unfolded state. In another embodiment, the memory metal material can be used to receive a control signal from an external source of the electroactive crystal. The controller 12 can use the

The memory metal material can be electrically connected to the controller and the electroactive element. For example, the memory metal material can be used as an antenna, a capacitor, an induction coil, or the like. In another embodiment, the memory metal material can be used for a charging power source. The material can be formed into a coil and/or an antenna and can be adapted to be wirelessly transmitted using an external device from one of the electroactive crystals. Power is used to inductively charge the power supply. In another embodiment, the memory metal material can be used to program and/or reprogram the controller and/or drive electronics. Metal materials that can be repelled by the earth can be, for example, titanium, palladium, nickel, nickel, titanium, copper, gold, cadmium, iron, copper, copper, titanium, titanium, nickel, titanium, gold, iron, zinc, copper, copper, copper Or iron manganese bismuth or any combination thereof. Referring again to Figures SA and 5C, the electroactive crystallography can include a sensing device 32 for detecting sensory information. The sensing device may include, for example, one or more of the following: a photovoltaic or uv sensitive photovoltaic cell, a tilt switch, a light sensor, a passive distance measuring device, a time-of-flight ranging 128668.doc - 19-200848001 device, an eye tracker, an observation detector, which detects a position that a user may observe, an accelerometer, a proximity switch, a physical switch, a manual override control, a capacitive switch, Switch when a user touches the bridge of the nose or the like. The sensing device may include two or more photodetector arrays with a focusing lens placed on each array for measuring distance. A difference and algorithm can be used to determine which array has the highest contrast and is used to determine the distance an object is placed from the electroactive crystal. The sensing device may include a range finder for detecting a distance to focus the electroactive crystallite; and/or a solar cell for detecting light incident around and/or incident on the electroactive crystal . The sensing device can include a microelectromechanical system (MEMS) gyroscope adapted to detect head tilt or cyclic rotation of the eye, as illustrated in Figure 6. Additionally, the sensing device can include a timing mechanism that can be combined with the gyroscope to distinguish a distance change from the perspective of the effect of the recline or other movement. In response to detection, the sensing device can trigger activation and/or activation of one or more of the electroactive crystals, for example, by varying the power applied thereto. The sensing device can be coupled directly or indirectly to the electronic devices and/or the electrical connections for electrically driving the electrodes. In a specific embodiment, the sensing device can indicate that the user is viewing the focus distance employed and can change or maintain the optical power of the electroactive element accordingly. In an example, if the nucleus is placed until the (4) is focused on a close range, the optical power of the component can be changed, and the sputum 兮兀 子 子 子 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该Doc -20- 200848001 Distance observation correction. In the present invention, the electroactive crystallite may further comprise an optical sorrow that transcends the remote switch (not shown) to manually override and switch the electroactive crystal. For example, the remote switch can activate, deactivate, or set a desired optical power. When the remote switch is activated, a remote switch signal can be sent to the electroactive crystal via an antenna formed by the memory metal material 28. Referring again to Figures 5C and 5D, the electroactive crystallite can include an opening 34 for allowing nutrients and cellular waste produced by the body to pass through the electroactive crystal. The openings may be semi-permeable membranes that allow material to pass therethrough based on the size of the knives of the materials. These openings and/or pores can be drilled, machined or stamped. Generally, the openings and pores may be located at non-electrical or otherwise non-critical regions of the electroactive crystal, such as near the bore axis where the electrodes do not extend or apply electrical power. Such openings are well known in the art regarding non-electrically active corneal inlays. 7A and 7B each show a front view (having an axis A) of one of the elastic electroactive crystals 2 and a sectional view AA of the elastic electroactive crystal 2 taken at the axis A. The 5 galvanic active crystal comprises an elastic film 4 and an electroactive H θ piece 6 embedded in the film. ® 7A includes # & 36 placed between the elastic film and the electroactive element. Thus, the element is surrounded by the envelope, which in turn is surrounded by the resilient outer casing. The envelope may be a water repellent, a protective barrier consisting of, for example, a hydrophilic acrylic material. In a specific embodiment, the elastomeric material can be comprised of, for example, polyoxo or a hydrophobic propylene S. material. In general, hydrophilic acrylic materials have a relatively low refractive index and are moderately rigid. In general, hydrophobic acrylic materials 128668.doc -21 - 200848001 have a relatively high refractive index and are elastic. The outer casing 4 may consist of a semi-permeable membrane. The outer casing may be coated with material from the anatomy of the eye. The barrier compatible materials may include, for example, polyvinylidene fluoride or non-hydrogel microporous perfluoroether.
